  1. If you have a solution of volatile liquid,then the vapour pressure exerted by each gas is directly proportional to their mole fraction.
    By henry’s law
    p1=p1(knot)x1
    p2=p2(knot)x2
    By rault’s law,P(total)=p1+p2
    =p1(knot)x1+p2(knot)x2
    =p1(knot)x1+p2(knot)(1-x1) [since x1+x2=1]
    then just simplify it a bit more to obtain the formula.
